I'm getting the following error message:

The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

I don't know what prompted this concern on my Windows 11-based laptop, but I only noticed this last night doing some research for another issue. I don't have any of my bookmarks showing up in the bookmarks section, nor will it allow me to click the star on any tab to bookmark the page. I have restarted and shut down my laptop several times and this is not solving the concern. Let me know if you need more information or if I need to start this inquiry again elsewhere, but again it sounds like the same concern.

I have included a screenshot of the exact error for accuracy's sake. Like everyone else here, I'm trying to get my bookmark and history access back up and running but not sure how to go about it.

I couldn't get past the first fix suggestion because I am not sure how to restart Firefox (https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional?as=u&utm_source=inproduct&redirectslug=The+bookmarks+and+history+system+will+not+be+functional&redirectlocale=en-US). I have restarted my laptop several times but the issue still persists.

Please advise.

Ironically, I am not having this issue on my older PC that is still operating on Windows 10. I can view history and access or add bookmarks with no concern to my knowledge.

Firefox had been a safe haven for anti-AI, and used to be my go-to search engine. If this AI bullshit continues, no one will respect or use the browser. Stop implementing AI garbage that steals data

I read firefox is dropping linux 32. Are there any alternatives?

I only use the internet to watch youtube videos.

I don't feel like having to buy a new laptop for this.

Is there a fix or workaround?

Mozilla, in their infinite wisdom, sent me a note about something new in firefox, by displaying it in a new instance of Firefox.

It wasn’t until I closed my normal session, that I realised a new instance of firefox was also running, and shut it down on.

In shutting the new instance down after my usual session, it overwrote all my normal tab settings🤬

Q1. Are my normal tab settings recoverable? Q2. Why did Mozilla think it a good idea to open a new instance of Firefox to send me information, rather than simply open a new tab.

NB This is in Windows 11

This is the 3rd time I have had to post this. I am getting very frustrated. I DO NOT want the search engine within my address bar. Nothing anyone from you "community" helped to disable the search engine in my address bar. Opera, Edge, Chrome, the user can disable the search engine in the address bar. Why is Firefox so different? And difficult?

I've been searching for three days now for a solution that will work to restore my profile from a crashed windows-7 machine to my new windows-11. Nothing listed in any forum or help desk works as described. I used to be able to just rename the folder to the exact file name on the new PC, but windows 11 won't let me do anything. It always needs admin permissions and even after I activated the admin account and assigned a password, I still cannot copy to the folder or rename the folder. Every attempt to do this on W-11 fails. It shouldn't be that hard and I'm tired of wasting days playing with this. I have important bookmarks, passwords etc. I want restored, and I need help. Nobody wants to pick up a phone anymore to assist!

I have never used "sync" because I have multiple PCs and each used for different applications and yes some go back to W-7, the operating system that actually worked well. Each PC has Firefox and a distinct bookmark file.

I went to "about:profiles" and created a new profile thinking I could copy to the new folder, but when i switched profiles I couldn't get back to the original default! HELP!

Previously downloading files did not close the source website. Now when downloading a file, the source website is closed. Requires logging into the source website for each file downloaded. How can closing the source website be stopped.

Several websites are not loading their content since yesterday. YouTube has a message "Try searching to get started" and even when I open a video, it won't play. X.com is not loading content in the pages. So far it's those two.

Firefox used to save unknown files according to the save files setting. i.e. ask where to save files. Now if opens unknown files as text in a new tab.

How can the correct behavior be restored?

Alternately, can the Linux snap be fixed to allow saving of new file types? {The procedure shown in https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file is not present in the firefox 141 snap.

This what you said: "Today we’re introducing a free built-in VPN in Firefox, a new IP-protection feature designed to keep you even more private while you browse. We’re starting by offering an industry-leading 50 gigabytes of free VPN-browsing each month." But all I see are the paid options. I want to try before I (might) buy. After all, you constantly preach that we have to be careful & trying to be careful.

Hello,

In the latest update I got it made everything into rounded corners. The Tabs and Settings windows as an example. How do I undo that?

I checked thoroughly in the appearance settings and dont see a way to do that. I specifically switched my entire world over to Firefox to get out of the rounded corner UI world only in time for this switch to happen. How do i undo it?

When I do this:

Click the menu button Fx89menuButton to open the menu panel. Click Bookmarks and then click the Manage bookmarks bar at the bottom. In the Library window, click the Import and Backup button and then select Restore.

I get a blank slate. No files listed.

When I go into the Profile, I see C:\Users\whatt\AppData\Roaming\Mozilla\Firefox\Profiles\shgdgxn6.default-release-1752271533405\bookmarkbackups

How do I restore bookmarks from that file?

I have a Brother DCP-L2550DW printer that is connected via a network cable. Any other browser, i.e. Edge or Chrome, seem to be able to connect and print just fine. Firefox fails to print and there is no information about why. I have checked Event Viewer, turned off all the extensions, tried the about:config to reset printer options. Every single suggestion I've found so far fails to fix it. I have a great deal invested in using Firefox (bookmarks, etc.) so I'd like to keep it as my default browser, but not being able to print is SO annoying. Any suggestions?
